Hello friends. In these photos I show you a work of identification of aragonite crystals that I made with colleagues of geosciences. Aragonite is a crystalline form of calcium carbonate, which can be found for example in cave speleothems. In this case we identified it for the first time in limestones in Cojímar, Havana. Aragonite has ornamental value and is used in clothing and jewelry.
